重庆矿山机器厂在毛主席无产阶级革命路线指引下,为贯彻毛主席关于“开发矿业” 的伟大号召,适应中小矿山发展需要,组成以工人为主体的三结合设计试制小组,经过一个多月的奋战,终于试制成功一种2JT1000/629型矿用提升绞车(简称—米绞车),经过两年多的矿山生产的实际应用,效果良好,受到使用单位的欢迎.该绞车根据中小矿山特点,并在分析JK系列基础上,参考BЛ系列1.2米绞车参数,确定采用了摆线行星减速器,内胀式安全制动器和电磁工作制动器新的结构.其主要技
Under the guidance of Chairman Mao’s proletarian revolutionary line, in order to carry forward Chairman Mao’s great call for “developing the mining industry” and meet the needs of the development of small and medium mines under the guidance of Chairman Mao’s proletarian revolutionary line, the Chongqing Mining Machinery Factory formed a trial-and-a-trial design team consisting mainly of workers. After more than a month After a successful trial, the 2JT1000 / 629 mine hoisting winch (referred to as -m winch), after more than two years of practical application of mine production, works well and is welcomed by the user. The winch according to the characteristics of small and medium mines, and Based on the analysis of the JK series, with reference to the parameters of the B-series 1.2-meter winch, the new structure of the cycloidal planetary reducer, the internal expansion type safety brake and the electromagnetic working brake is determined.
